Temperature numbers for Livermore are from a link from the National Weather
Service averaged from 1930 to 2001. The Dublin city web site appears to use
the Livermore numbers.

*Tri Valley includes Livermore, Pleasanton, Sunol, Dublin, and
San Ramon for the numbers above.
Total and Tri-Valley total for percentages and median age are calculated using
weighted average.

Some Observations:
The Tri-Valley area grew at about double the
National and California averages from 1990 to 2000. 28.5% over 10 years is
just over a 2.5% per year growth. The National average was about 1.25% per
year.

The Tri-Valley has fewer people in the 18-24 age
group and far fewer people over age 65 than than the National and California
averages.

The Tri-Valley has more people in the Under 18
age group (especially Livermore & Pleasanton) and much higher in the 25-44 age
group than the National average.

The Tri-Valley has far higher than the National
or California averages for family household percentage.

These numbers suggest that the Tri-Valley is home
to a lot of young families, which is what would be expected.

The following is a list of Pacific Bell exchanges (prefixes) used in each city.
Livermore, Pleasanton, and Sunol have their own switches. Dublin and San
Ramon are combined, and share exchanges.

This list does not include cell phone exchanges, or non-Pacific Bell exchanges
(ATT Broadband), although other carriers will use some of these exchanges, when phone
service has been switched between carriers and the same number is maintained.

The exchange list was obtained from Pacific Bell on 11/5/02. New exchanges
are added periodically.

In general the exchanges
are contained within a local switch, and are not shared
between them. Moving from Livermore to Pleasanton, for instance, requires
a phone number change.

Note that some business numbers in San Ramon have been noticed with Danville
exchanges.
